SASH FASTENER.

Application filed February V12, 1927.

My present inventioinin its broad respect, has reference to improvements1n fastening devices for window sashes of the type de signed, when in anactive status, to prevent movement of any of several cooperating sashesto an open position, or to prevent any relative change in the positionof several sashes except toward a closed position after having beenplaced in a predetermined open position.

More particularly it is my purpose to provide a simple and effectivesash fastener which may be readily placed in a passive status to permitopening offany of seyeral sashes, or to permit the opening of a singlesash with Vrespect to its frame, and which when placed in an activestatus will permit only closing movement of the sash or sashes. To' thisend I have provided an arm which is both pivotally and slidably mountedon a sash and which is acted upon by a unique double acting springdevice which serves to retain said arm either in an active, or securingposition, with respect to a cooperating sash or with respect lto theframe of a window, or the like,`or to retain said arm in a passive,orvunsecured position.

Other and equally important advantages of my fastener may be brieflydefined as follows: first, the securing arm and actuating spring beforereferred to, and all other parts of my invention, are assembled in asingle unit for attachment to but one of two cooperating sashes therebydispensing with the use of two units, one on each of two cooperatingsashes, as has been the usual practice heretofore; second, rubberorvother inherently resilient means are provided on the securing arm forpositive engagement with an adjacent surface of a cooperating sash,without marring the surface thereof. to induce through theinstrumentality of said arm a securing wedging and prevent relativeopening movement of the sashes, and furthermore to prevent rattling ofsaid sashes, and, third, my device inv assembly is composed of but fourparts, none of which are intricate or fragile or likely to become out oforder.

One embdiment of my invention is illusstrated by way of example in theaccompanying drawings wherein Figure l is a perspective view of a doublesash window frame assembly showing' my fastener applied thereto; Fig. 2is a perspective view of my fastener, a portion of a sash is its passiveposition.

being also shown to illustrate its application; Fig. 3 is a longitudinalthrough my fastener; F ig. 4f is a transverse section; Fig. 5 is adetail of the carriage; `Fig. G is a detail of the double actingspring', and Fig. 7 is a detail view of plate.

ln the drawings wherein like characters of reference are used todesignate like and sin lar parts throughout the several views:

The window frame is designated by A, and the respective upper and lowercooperating sashes by B and C. These are conventionally shown and may beof any approved type.

The. plate 1 of my fastener has suitable screw holes 2 through which aredisposed the screws by which the plate is attached to the lower .sash C.A U-'shaped housing 3 is .lined on the plate, rand one end thereof isclosed by an upwardly bent ear a integral with the plate 1, the otherend of the housing is open for the reception of a cylindrical carriage 5having ak reduced shank 6 which extends through and is adapted to workin an opening in the ear i when the ca 'riage is moved lengthwise of thehousing. A coil spring 7 is disposed about the shank (i and has one end8 engaged with the ear 4 and the other end 9 with the carriage 5. a slot10 being provided in the carriage for that purpose. rEhe housing 3 hasformed therein a4 bayonet slot 11 through which extends for screwthreaded engagement with the carriage 5, an arm 12, the free end ofwhich is provided with a flanged head 13. f A pad 1d of rubber or othersuitable inherent resilient material is retained on the head of the arm12 by the flange thereof, as shown in Fig. et.

ln assembling-my fastener, the spring -7 is engaged with the carriage 5and the carriage given a turn to place the spring under tension, the arm12 is then attached to the carriage, and since the spring is undertension the arm will be normallyurged to the position shown in dottedlines in Fig. l, which is its active position. The end of the carriageis provided with a slot 15 for receiving a screw-driver to turn thesaine, and when so turned against the tension of the spring 7, thecarriage will be urged forward and lock the arms in the bayonet slot 11in the position shown in full lines, in Fig. 4, which It will thus beseen that the spring 7 is double acting in that it urges the arm 12 bothto its active position and to its passive` position, this end beingsectionaccomplished by simply turning the carriage.

The carriage may also be turned by simplyl ln operation, the fastener isplaced in itsl passive position and the Window opened (by raising orlowering either or both of the sashes B and C) the fastener is thenreleased and will engage the adjacent surface of the cooperating sash inwhich position 'further opening' of 'the Window will be prevented by thewe(bring-securing action of the arm l2. rlhe window may be closedhowever, Without distiubingi` the fastener since closing' movement doesnot aii'ect such 'tif'edngingg action. Furthermore, Where but one sashis operative my fastener` may be disposed to engage the adjacent surfaceof the frame, and in any case marring or scratching; of the` surfaceengaged by the fastener is absolutely prevented by the pad.

l claim:

l. A. Window fastener comprising',` a inember movable in one directionto a position to prevent relative openingl movement of either or both ofa pair of sashos, and in another direction to release the sashes, adouble actinf*Y member adapted to urge said member either to its activeor to its passive position, and said member being movable against theaction of said double acting` member to release it from its activeposition.

2. An Window fastener comprising; an arm movable in one direction toprevent relative opening' movement of either or both of a pair ofsashes, and in another direction to release said sashes, a double actingspring adapted to urge said arm to its active or to its passiveposition, and said arm bein g1' movable against the action of saiddouble acting?,` spring; to release it from its active position.

3. A Window fastener comprising' a member adapted for movement in oneplane to a position to prevent relative opening' movement of either orboth of a pair of sashes, and to release said sashes, and in anotherplane to a normal passive position, a double acting; spring' adapted tourge said member to its active position or to its passive posi-Lese-,35o

tion, and said member being movable against the action of said doubleacting spring to dispose it for movement in the last mentioned plane toa normal passive position.

e. it Window fastener comprising a movable body, an arm carried by saidbody to vedgingly engage an adjacent-structure t secure a Window in anopen position, said body being` movable in one direction to release saidarm from its Wedging' position and in another direction to secure saidarm in a passive position, and a double acting spring for urging' saidbody to move in the direction for disposing` said arm in a passiveposition and against the direction `of movement of from its Wede'ingposition. Y

A Window fastener comprising` a movable body, an arm carried by thebody, a sgring; actingrupon the body to resist movement of the body inone direction and urge movement of the body in a direction atan saidbody to release the arm angle to the first direction of movement 0fl i'he body.

6. i window fastener comprising a movable body,` an arm carried by thebody, a spring' acting' upon the body yto resist movement of the body inonedirection and urge movement of the body in a direction at an angle tothe iirst direction of movement of the body, and a casing for the bodyformedV with bayonet slot through which thearm entends for engagementWith the body.

7. A Window fastener comprisingl a movable body for arrangement upon asash, an arm carried by the body and adapted to enan adjacent structureto prevent openmp; movement of the sash, said arm being provided With acushioned head, a spring acting npon the body to resist movement of thebody to release the arm from engagement with the adjacent structure, andurge movement of the body in a direction at an angle to the firstdirection of movement of the body,`
